Life takes shape with the motion of a single cell. In response to signals from certain proteins and enzymes, a cell can start ...

Engineered starfish oocytes shape-shift in response to light, may enable the design of synthetic, light-activated cells for ...

This monomer inhibits the enzyme with high affinity (K i = 40 μM) holding it in place near the growing particle and hence allowing the polymer chains to adapt to the shape of the protein surface ...

In an organism, the active site of each enzyme is a different shape. It is a perfect match to the shape of the substrate molecule, or molecules. This is essential to the enzyme being able to work.

Different enzymes contain up to 20 different amino acids linked together to form a chain which then folds into the globular enzyme shape. Enzymes have active sites which only match specific ...

The researchers observed that light activated the enzyme, causing predictable cell movements. For example, specific light ...

Enzymes are proteins that can change shape and therefore become active or inactive. An activator molecule (green pentagon) can bind to an enzyme (light green puzzle shape) and change its overall ...
